DELIVERY MECHANISM FOR PRINTING-PRESSES.

To all 'whom it may concern.'

Be it known that-we, HARRY Lnwis and CHARLES J. lVnIGH'r, both of Niles, inthe county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Delivery Mechanismfor Printing- Presses; andwe do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertaius to make and use the same..-

The primary object of this invention is to provide an improved deliverer lfor printing machines and the like capable of automatically delivering the printed stock alternately in different plles, or all of the stock in a single pile at one of a plurality of points.

The invention contemplates the 'employment of at least two separate stock recelvers, preferably n the form of removable trays, and improved means for automatically discharging tlie stock successively into the receivers, or -all of the stock into laasingle receiver.

The invention will be hereinafter fully set forth and particularly pointed out -in the claims;

In the accompanying drawings, Figure 1 is a side elevation showing the deliverer attached to a printing press. Fig.' 2is a central longitudinal sectional view. Fig. 3 is a transverse section. Fig. 4 .is a fragmentary view','on an enlarged-scale, showing the parts in position to secure the discharge of thestock alternately into the two trays, the gate being shown raised in full lines and lowered in dotted lines. Fig. 5 is a view of the same parts showing the gate fixedly held in its lowered position to insure the discharge of the stock into the inner tray. Fig.

G shows the gate ixedly held in its open xpo'-- sition "to allow the stock to bedischar'ged into the outer tray. v

Referring to drawings, 1 designates a main frame 'or support which is shown in. the form of a wheeled carriage which is designed to be detachably connected to a ress frame. This frame supports suitable s afts carrying sprocket wheelswith which engage opposite sprocket chains 2, and these chains support a series of spaced apart stock carriers 3 after the manner contemplated by Letters Patent No. 726,161 issued' to 'Charles G. Harris April 21, 1903. These carriers are preferably three .in number, 'and areshown as composed of tapes fastened by Specication of Letters Patent,

means of suitable collars on cross rods et secured at their ends to the endless chains 2. These carriers, or more properly speaking, thelr carrying chains 2, are d rivlen .by any suitable means, (preferably bv the press gearing) at such 'speed as to properly position one of the carriers in proper relation to the press cylinders to receive a sheet at each cycle of .o )eration of'the press.

Locate between the upper and lower flights of the carrier chain 2 are two stock receivers 5 which are shown in the form of separate trays, which latter are removable from their rests 6 (see Fig. 2) through one side of the frame, and their walls are usually made 'a'djustable so as to accommodate stock of varying proportions. 7 and 8 are gates which extend transversely of the deliverer and'intersect the plane c-f the carriers imtheimoutward travel so as to cause sheets of stock sup orted by the latter to be stripped olf into the receivers. The gate 7 is located about midway of the deliverer, that is to say, at'a poi y-above the adjacent sidesof the two trays, w ile the gate 8 is located abdve the outer side of the' outer tray. The particular formation of the gates is immaterial, and the same may be widely varied without departing from the spirit of our invention. As shown in Fig.

3 each gate comprises a plate having a series" By means of handles 14 either shaft 10 may be manuallyl turned to raise the respective gate as against the. tensionofits retaining spring 12. So far as concerns the outer gate 8 it is never raised out ofthe path of the stock except when vthe attendant desires to examine a piece of stock, in which event by manipulating the handle l-l the stock will be conveyed by itsl carrier to the outer end of the deliverer and fall therefrom as the carrier turns to start on its return travel.

--The. inner gate is intended to be permanently held -in its lowered position when the stock is to be dis'harged into the inner tray; to be permanently. held in its raised posi- The finger plates are pivoted on a stud carried by its short arm 21, which latter is carried by a shaft 22 having its bearings in the sides of frame 1 and extendin transversely thereof with handles 23 on lts epds'so that the position of lever 19 may be readily shifted at either side ofthe machine. The le'ver is intended to occupy any one of the three positions shown in Figs. 4, 5-and 6. Vhen lever 19 is in its approximately vertical position, Fig.

' whichis revolved at half the speed of the,

4, gate 7 will be periodically'operated to cause the sheets to drop alternately in the two trays. A constantly rotating cam 25,

press cylinder, is designed to engage a roller 26 carried by lever 19` and move 1t into the full line position, thereby swinging the gate 7 to allow the sheet to pass with its carrier and to be arrested by gate 8 and discharged in the outertray.- -The proud portion of the cam is a little more than the equivalent of the length of afu'll sized sheet, thus allowing time for the largest sheet to pass before the proud portion of the cam disengages the roller 26, whereupon the gate is returned to its lowered position, shown in dotted lines Fig. 6, b the action of spring 12. The low part of t e cam is also equal to the length of alfull sized sheet, and hence the lever -19 remains in-the dotted line position for a sufficient time ,to enablev the gate 7 to cause the next sheet to drop in the inner tray. The stud 20 fits in a groove 26* of a plate 26b when the lever is set as in Fig. 4 tohold the Y short arm in its vertical positron.

`Fi 5 showsgate 7 fixedly held in 'its close or lowered position for which purpose lever 19 is moved downwardly and thrown into a rearwardly inclined position by the partial rotation of shaft 22, the downward movement being limited by a stop 27. VVheJi the lever is in this position roller 26 is outl -of the path of the actuating cam .25. lVhen 1t is desired to discharge all the stock into the outer tray, the lever 19 is thrown into the forwardly inclined position 'shown in Fig. 6, shaft 22 being turned in the opposite direction 'to that re uired for giving the lever the position x s iown in Fig. 5. When being thrown into the position shown in Fig. 6 the lever 19 by engaging a stop -28, is forwardly inclined to permanently hold gate 7 in its opened or raised position. In this instance, also, the cam 25 is incapable of actuating the lever 19.

30 designates fingers which are designed to knock downward the forward ends of the sheets, toward the pile, as the carriers pass `from thereunder. -lVe preferably employ two fingers in connection with each gate, but the number is immaterial.,` They are shown as formed from metallic plates adjustably mounted on a rock shaft 31 having its bearings in the main frame, and at their forward ends these fingers are up-turned and extend between the fingers of the gates. They are so positioned that they are under slight tension of springs 32 when engaged and slightly raised by the carrier tapes. By extending the ends of the fingers through the gates they ,willinot interfere with the front edge of the sheet at'any time, but upon the rearward portion of a carrier passing from beneath the fingers the latter will strike ,against the front end of the sheet and direct it toward the pile. To enable the fingers to be elevated out of the way when either gate is raised, an arm 33 of each rocker shaft 31 is connected by means of a link 34 to an arm 35 fastened to the gateshaft 10.

We have shown in Figs. 1 and 2 an upper series of tapes orstrings 40 carried by suitable.pul leys at the inner and outer ends of the main frame, and driven by any suitable means, land preferably at a slightly greater speed thanl e carriers, the urpose of these tapes or strings being to eep the sheets, especially when they have a tendency to curl upwardly, down against the carriers.

It will .be understood that the lever actuating am 25 may be rotated by any suitable means. It is shown mounted on the shaft of agear wheel41 which is driven by a pinion 42 on the shaft ofthe sprocket wheel which is gearing.

The advantages of the present 'invention will be readily appreciated by those skilled in the art. It will be seen that by means thereof separate pieces of stock may be alternately deposited in two trays, or all of them may be deposited in either of thetrays,

it only being necessary to partially turn a single shaft to bring about a change in the other respects the operation of the machine automatic. Single, flat, unfolded sheets deposited on the carriers will. be discharged therefrom tail end foremost through the gaps formed in the traveling device between the several carriers.
